Be creative! ! ! Design a simple invention with sensors.

Put a pressure sensor under the doormat, and the wire is connected to the controller to control the light switch or other electrical equipment. The owner lights up automatically after entering the room, and other household appliances such as air conditioners start automatically.

It is a detection device, which can sense the information of the measured current, and can convert the sensed information into electrical signals meeting certain standards or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of sensors include miniaturization, digitalization, intelligence, multifunction, systematization and networking. It not only promotes the transformation and upgrading of traditional industries, but also may establish new industries, thus becoming a new economic growth point in 2 1 century. Miniaturization is based on MEMS technology, and has been successfully applied to silicon devices to make silicon pressure sensors.
